Drive west from San Martín de los Andes into Lanín National Park for a five-hour loop that mixes Patagonian plains, a short forest hike and a 65-foot waterfall. Expect easy walking, big lake views and Mapuche cultural notes along the way.
More ways to explore the area's outdoor wonders
The minivan peels away from San Martín de los Andes and the town's pastel houses thin into open sky. Within minutes the road opens onto the Pampa de Trompul: a wind-sculpted plain where grass lies flat and stone outcrops punctuate the horizon. Here the landscape speaks in simple, blunt lines — Cerro Colorado and the extinct shoulders of Savannah Mountain watch in the distance — while the guide points out Piedra de Trompul, a rock the Mapuche long read as a weather oracle.

Wear grippy shoes
The 30-minute trail to Chachín has mud and exposed roots—sturdy hiking shoes with good tread make the short climb far more comfortable.
Bring at least 1L of water
There are no services on the trail; a reusable bottle keeps you hydrated during the hikes and lakeside stops.
Carry ID for the border stop
You won’t be crossing into Chile, but having your passport or ID is useful for photos near the historic border buildings and for any logistical checks.
Time your photos
Morning or late-afternoon light flatters the lakes and the forest; mid-day is harsher but fine for waterfall shots when exposure is adjusted.
Waterproof jacket
Spring rains and wind can arrive suddenly—waterproof layers keep you warm and dry.
